In this biology activity (page 8 of the PDF), learners will determine whether they are "tasters" or "non-tasters", test selected individuals from their families and peer group for the trait, and chart

In this game, learners create flash cards with an image on one side (of an animal, for example) and the sound that animal makes on the other.

In this activity, learners create a simple “top” from a CD, marble and bottle cap, and use it as a spinning platform for a variety of illusion-generating patterns.

In this activity, learners explore what happens when polarized white light passes through a sugar solution.

In this activity, learners create a traditional Mexican noisemaker (a matraca) using cardboard, craft sticks, and a wooden dowel.

In this engineering design challenge, learners animate a facial expression and make a machine (zoetrope) that plays the animation back.

This activity (on page 2) explores how sensing is part of robotics. Learners try tying their shoes with different constraints.

In this optics activity, learners discover basic lens-making techniques by using a tennis ball to make a lens out of ice.

In this group activity, learners see and hear the speed of sound. A learner designated the "gonger" hits a gong, once every second, as the rest of the group watches and listens from a distance.

In this activity, learners experiment with the Stroop Effect by challenging themselves and others to try and read a list of colors as quickly and accurately as possible, with a twist.

In this activity, learners construct a three-dimensional ambiguous cube to explore visual illusions and how our brains interpret or misinterpret information.

In this activity about olfaction (9th activity on the page), learners smell 10 different items with different odors, including some edible food items.

Learners use a mortar and pestle to extract clove oil from cloves using denatured alcohol. They put this oil on paper, which they can take home.

In this activity, learners construct an indoors obstacle course and discover how using an eye patch can help them complete the course in the dark.

In this neuroscience activity (4th activity on the page), learners make their own set of Von Frey hairs to test detection thresholds.

In this activity (10th activity on the page) about the sense of touch, learners make Braille letters out of cork or cardboard and map pins.

This fun and simple hands-on astronomy activity lets learners explore the difference between telescope magnification and resolution.

In this activity about depth perception, learners create an optical illusion in a shoe box.

In this activity about olfaction (8th activity on the page), learners smell 10 different items with different odors. Then they try to identify the smells when they are mixed together.

In this activity (1st activity on the page), learners explore their sense of taste and the structure of the tongue by taste-testing various foods.
